Updated, but not completely, December 11, 2020. See free and open-source Mac statistics software
Apple’s Mac system updates have left certain software behind. This list is to make it easier to figure out whether statistics software is (a) ready for OS 10.15 and beyond, (b) Mojave-safe — that is, OK with OS 10.14, and (c) signed, so you won’t see a scary “unidentified developer” message like the one below. If we leave out information, it’s because we don’t know. If you are a developer or user and want to update this list, please let us know!
M1 and Big Sur compatibility are slowly being added to this list. Three dead packages were taken out on 12/11/2020.
Acastat and Clarity: Mojave/Catalina safe, 64-bit, signed
DataDesk: Mojave/Catalina safe, 64-bit, signed
DataGraph: Mojave/Catalina safe, 64-bit, signed
Easy Chi-Square Calculator: Mojave safe, 64-bit, signed
G*Power: 64-bit, signed. Version 18.104.22.168 appears to be the most recent, and is compatible up to High Sierra.
Jamovi: 64-bit, signed
JASP: 64-bit, not signed
JMP: 64-bit, signed
Kaleidagraph: Unsigned. Not 32-bit; Catalina and Big Sur incompatible. Not updated since Mojave’s release. No timetable (as of 12/11/2020) on when a new version may be available, but the company said it was coming and suggested virtualization in the meantime.
MathStatica: Runs on whatever Mathematica runs. Mathematica’s site does not mention Mojave.
PAST: Mojave/Catalina safe, 64-bit, but unsigned
PSPP: Unsigned binary; 64-bit. Version 1.4 is safe for Mojave and Catalina. Source code, MacPorts, and Homebrew versions are available so you can build it yourself if needed. M1 optimization is unlikely to be fast, if it arrives at all.
R (CRAN): 64-bit, signed
Regress+: 64-bit, signed; tested on Mojave
SageMath: 64-bit. Have not tested for signing or Mojave (it's 3.5 GB); not listed on site.
SOFA: Unsigned but 64-bit; no new release since well before Mojave was launched. The Sofa people posted a note saying they need help packaging 1.5 for the Mac—in May 2019. (This note was added in December 2020.) In short, it may be best to look somewhere else.
SPSS: 64-bit, signed, safe for Mojave with latest “Fixpack” (as of version 25)
Stata: 64-bit, signed, safe for Mojave
StatCalc (from Acastat): 64-bit, signed, Mojave compatible
Wizard: Mojave safe, 64-bit, signed; Big Sur and M1 compatibility promised
Wizard 2: Catalina and Big Sur safe, M1 and Intel safe
